As a rule, employees should get paid time and a half after 44 hours a week on the job, according to the Employment Standards Act.
But in 2014, more than one million people in the province worked overtime, and 59 per cent of them did not get any pay whatsoever for it, Statistics Canada data shows.
This, experts say, is partly because enforcement is poor. But in Ontario, a variety of occupations don't even have the right to overtime pay, including farmworkers, flower growers, IT workers, fishers and accountants. Managers are also not entitled to overtime.
Vladimir Sanchez Rivera, a 45-year-old seasonal farmworker in the Niagara region, says he has worked 96-hour weeks doing back-breaking labour picking cucumbers and other produce.
